Three-time Olympic champion Jason Kenny crashed at high speed on day two of the Track World Cup in Glasgow as the hosts missed out on gold on another eventful day at the Sir Chris Hoy Velodrome.

Jess Varnish and Becky James, who combined to win team sprint gold on day one, won individual sprint silver and bronze, respectively, but Kenny's bid for the keirin title ended when he hit the Siberian pine at 75 kilometres per hour.

The 24-year-old from Bolton was able to ride around to show there was no significant damage and is scheduled to compete in the sprint on Sunday.

Taking a tumble: Home favourite Jason Kenny crashed out of the keirin final

British Cycling sprint coach Iain Dyer said: 'He looks a bit second hand and he feels a little bit second hand. Nothing's broken. He's taken a lot of skin off. That skinsuit's already in the bin.'

The Olympic sprint champion was supreme in the early rounds, but had to wait for his chance in the final due to a temperamental motor-paced Derny bike.

When the race did get under way at the third attempt, Kenny was well positioned with one lap to go and was making his move on the back straight when he lost his balance and tumbled to the track.

Kenny took Quentin Lafargue with him and both riders were quickly on their feet nursing skin abrasions, with the Frenchman undergoing assessment by medical staff.

Dyer added: 'He (Kenny) got caught in a bit of a drag race with Stefan Boetticher, the German guy, which he didn't really want to take on at that point on the race.

'He was looking for the wheel, looking to get into the slipstream again and he was keeping an eye on Lafargue behind him.

'I think both Boetticher and Jason were looking behind at exactly the same time, both moved in the same direction and Jason never saw it coming, he just smelt it and heard it.'

Partisan crowd: Jessica Varnish and Rebecca James went against each other in sprint semi-final

Kenny was not the only Briton to crash out of the keirin.

Lewis Oliva, competing for Wales-Team USN, crashed on the final corner of his semi-final heat and was taken away on a stretcher. He was diagnosed with mild concussion and will be monitored by team medical staff overnight.

There was a happier conclusion to the day for Varnish.

The 21-year-old focused on the specialist starting role for the team sprint for the Olympics, but her 2012 Games ended in disappointed following a takeover infringement.

Following the retirement of Victoria Pendleton, Varnish is diversifying and riding all four sprint events in Glasgow.

She qualified second fastest and negotiated the early rounds successfully before edging to a 2-1 semi-final win over James.

Varnish was then beaten 2-0 by Kristina Vogel of Germany in the final.

'It was good,' Varnish said. 'It's nice to be actually in a final. I just want to be able to step it up another level now. I'm not in the best shape, so I've not played all my cards.

'It's really nice to gain experience at the moment and build on to the worlds (in Minsk in February).'

James, who like Varnish is to ride the keirin on the final day, responded from her semi-final defeat to beat Hong Kong's Lee Wai Sze in the ride-off for bronze.

The 20-year-old Commonwealth medallist said: 'It's been such a hard day, getting three rides up against Jess was really tough and then missing out on the gold/silver ride-off was hard.

'I had to get my head round it and I did not want to come away with no medal, so I'm really happy.'

Jonathan Dibben placed fifth in the men's omnium as Germany's Lucas Liss won by one point from world champion Glenn O'Shea of Australia.

Dibben was third in the final event, the one-kilometre time-trial, which Liss won to secure gold.

The men's individual pursuit was won by Denmark's Lasse Hansen in four minutes 20.875 seconds, with Ireland's Martyn Irvine second in 4mins 22.745secs, a significant personal best.

Olympic and world champion Laura Trott was in fourth place at the halfway stage of the women's omnium.

The 20-year-old was fourth in the flying lap, ninth in the points race and won the elimination race, an event she appears to have mastered.

Australia's Ashlee Ankudinoff was in first place, but just a point better off than Trott with three events to go.
